Spring操作事务的方式

      笔者列举了常见的srping操作数据库的问题，列举了两种操作事务的方式(XML配置的方式和注解的方式)

希望能给学习spring框架或开发中的小伙伴一点点帮助。谢谢

一.spring与JDBC整合

xml version = "1.0" encoding = "UTF-8" ?>

< beans xmlns = " http://www.springframework.org/schema/beans" ;

      xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance" ;          xmlns:context = " http://www.springframework.org/schema/context" ;

      xsi:schemaLocation = " http://www.springframework.org/schema/beans

         http://www.springframework.org/schema/beans/spring-beans-3.2.xsd

         http://www.springframework.org/schema/context

         http://www.springframework.org/schema/context/spring-context-3.2.xsd" ; >

     

      < bean name = "dao" class = "com.briup.jdbc.UserDaoImplByJDBC" >

           < property name = "dateSource" ref = "dataSource2" > property >

      bean >

     

  

     

      < context:property-placeholder location = "jdbc.properties" />

      < bean id = "dataSource2" class = "org.apache.commons.dbcp.BasicDataSource" >

           < property name = "driverClassName" value = "${jdbc.driverClassName}" />

           < property name = "url" value = "${jdbc.url}" />

           < property name = "username" value = "${jdbc.username}" />

           < property name = "password" value = "${jdbc.password}" />

          

           < property name = "maxActive" value = "80" />

          

           < property name = "maxIdle" value = "20" />

          

           < property name = "maxWait" value = "3000" />

      bean >

     

      < bean name = "dataSource"

           class = "oracle.jdbc.pool.OracleConnectionPoolDataSource" >

           < property name = "networkProtocol" value = "tcp" />

           < property name = "databaseName" value = "XE" />

           < property name = "driverType" value = "thin" />

           < property name = "portNumber" value = "1521" />

           < property name = "user" value = "oracle" />

           < property name = "serverName" value = "127.0.0.1" />

           < property name = "password" value = "oracle" />

      bean >

二.Spring与Mybatis整合(常用的方式)

mybatis-config.xml 配置

xml version = "1.0" encoding = "utf-8" ?>

DOCTYPE configuration

        PUBLIC "-// mybatis.org//DTD Config 3.0//EN"

                " http://mybatis.org/dtd/mybatis-3-config.dtd" ; >

< configuration >

      < typeAliases >

           < package name = "com.briup.pojo" />

      typeAliases >

      < mappers >

           < mapper resource = "com/briup/mybatis/userMapper.xml" />

      mappers >

configuration >

mapper映射文件配置

xml version = "1.0" encoding = "UTF-8" ?>

               DOCTYPE mapper PUBLIC "-// mybatis.org//DTD Mapper 3.0//EN"

                " http://mybatis.org/dtd/mybatis-3-mapper.dtd" ; >

< mapper namespace = "com.briup.dao.IUserDao" >

      < insert id = "addUser" parameterType = "user" >

          insert into a_user

          values(#{id},#{name},#{age})

      insert >

      < select id = "listUser" resultType = "user" >

          select id,name,age from a_user

      select >

mapper >

spring XML配置

xml version = "1.0" encoding = "UTF-8" ?>

< beans xmlns = " http://www.springframework.org/schema/beans" ;

      xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance" ; xmlns:context = " http://www.springframework.org/schema/context" ;

      xsi:schemaLocation = " http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.2.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.2.xsd" ; >

     

     

      < context:property-placeholder location = "jdbc.properties" />

      < bean id = "dataSource" class = "org.apache.commons.dbcp.BasicDataSource" >

           < property name = "driverClassName" value = "${jdbc.driverClassName}" />

           < property name = "url" value = "${jdbc.url}" />

           < property name = "username" value = "${jdbc.username}" />

           < property name = "password" value = "${jdbc.password}" />

          

           < property name = "maxActive" value = "80" />

          

           < property name = "maxIdle" value = "20" />

          

           < property name = "maxWait" value = "3000" />

      bean >

     

      < bean id = "factory" class = "org.mybatis.spring.SqlSessionFactoryBean" >

           < property name = "dataSource" ref = "dataSource" />

          

           < property name = "configLocation" value = "classpath:mybatis-config.xml" />

      bean >

     

      < bean class = "org.mybatis.spring.mapper.MapperScannerConfigurer" >

        < property name = "basePackage" value = "com.briup.dao" > property >

        < property name = "sqlSessionFactory" ref = "factory" > property >

    bean >
